| inferior frontal sulcus | A sagittal fissure on the lateral convex surface of each frontal lobe of the cerebrum demarcating the middle from the inferior frontal gyrus. Synonym: sulcus frontalis inferior. (05 Mar 2000) |
|---|---|
| internal surface of frontal bone | The surface of the frontal bone that contributes to the wall of the cranial cavity. Synonym: facies interna ossis frontalis. (05 Mar 2000) |
| orbital part of frontal bone | The portion of the frontal bone that contributes to the formation of the orbits; the most rostral of three cortical convolutions that togetther form the inferior frontal gyrus. Synonym: pars orbitalis ossis frontalis. (05 Mar 2000) |
| epilepsy, frontal lobe | Epileptic seizures arising from the frontal lobe characterised by simple partial, complex partial, secondary generalised seizures, or combinations of these. The seizures, which are short in duration, may occur several times a day, mostly during sleep. Affected individuals usually have prominent motor manifestations which are tonic or postural, complex gestational automatisms at the onset, and fall to the ground when the discharge is bilateral. Status epilepticus is a frequent complication. (12 Dec 1998) |
| external surface of frontal bone | The convex outer surface of the frontal bone. Synonym: facies externa ossis frontalis. (05 Mar 2000) |
| zygomatic process of frontal bone | The massive projection of the frontal bone that joins the zygomatic bone to form the lateral margin of the orbit. Synonym: processus zygomaticus ossis frontalis. (05 Mar 2000) |
| foramen caecum of frontal bone | <anatomy> Blind or caecal foramen of the frontal bone; the blind foramen formed immediately anterior to the crista galli by a notch at the lower end of the frontal crest and its articulation with the ethmoid bone. It is insignificant postnatally, but gives passage to vessels during development. Synonym: foramen caecum ossis frontalis, blind foramen of frontal bone, caecal foramen of frontal bone.

Frontale an ornament for the forehead, frontlet. See Front. Source: Websters Dictionary (01 Mar 1998) |
| frontal angle of parietal bone | The anterior superior angle of the parietal bone. Synonym: angulus frontalis ossis parietalis. (05 Mar 2000) |
| frontal area | Cortex of the frontal lobe of the cerebral hemisphere, originally, the entire cortical expanse anterior to the central sulcus, including the agranular motor and premotor cortex (Brodmann's areas 4 and 6), the dysgranular cortex (area 8), and the granular frontal (prefrontal) cortex anterior to the latter, now more often refers to the granular frontal (prefrontal) cortex. Synonym: frontal area. (05 Mar 2000) |
| frontal artery | <anatomy, artery> Origin, ophthalmic; distribution, anterior portion of scalp; anastomoses, branches of supraorbital. Synonym: arteria supratrochlearis, arteria frontalis, frontal artery. (05 Mar 2000) |
| frontal belly of occipitofrontalis muscle | <anatomy> The anterior belly of the occipitofrontalis muscle. See: occipitofrontalis muscle. Synonym: venter frontalis musculi occipitofrontalis, frontalis muscle. (05 Mar 2000) |
| frontal bone | The large single bone forming the forehead and the upper margin and roof of the orbit on either side; it articulates with the parietal, nasal, ethmoid, maxillary, and zygomatic bones, and with the lesser wings of the sphenoid. Synonym: os frontale, coronale. (05 Mar 2000) |
| frontal border | Edge of a bone which articulates with the frontal bone. See: frontal border of parietal bone, frontal border of sphenoid bone. Synonym: margo frontalis, frontal margin. (05 Mar 2000) |
